(Cl. 211'13) This invention relatesto the loading and transportation of yarn beams and the like. Moreparticularly this invention concerns a shipping rack or support for aplurality of heavy spools or beams of yarn, which rack may be easily andsafely loaded with the heavy beams of yarn and transported in a carrieror vehicle. With the use of this beam support rack, the usual damageincurred by the yarn stored on stacked beams through shifting of theload during transit is avoided. This application is a continuation inpart of my copending application Serial No, 750,454, tiled May 26, 1947,which has now become abandoned.

The problem which gave rise to the present invention was thetransportation of large spools of rayon yarn or the like from themanufacturing plant to the customers and converters. These spools orbeams weight approximately 200 to 350 pounds each and in loading andtransporting the spools considerable diiiiculty has been experienced inthe past in arranging and supporting the spools in the truck or car bodyin a manner such as to -avoid shifting and resultant damage duringtransportation. Obviously, the question of space plays an important partin the problem and it became practically essential to load the spools inrows and in superimposed relation. Despite extreme care and more or lesscomplicated reinforcing and chocking structures used in the loading, thelosses resulting from shifting of the spools and crushing or bruising ofa relatively large quantity of yarn carried by the spools or beams havebeen considerable. The damaged yarn is returned to the producer since itcannot be used by the converter.

The primary object of the present invention therefore is to provide anapparatus for securing relatively large heavy spools, beams or similarshaped objects in a manner such as to avoid shifting and resultantdamage `to the contents of the spools during transportation.

Another object of the invention is to provide a rack or support whichcan be used to safely handle spools of thread such as rayon thread whichis easily bruised or otherwise damaged.

Another object is to provide a rack or support for a plurality ofrelatively large and heavy spool-shaped objects or the like whereby thespools may Ibe loaded in superimposed relationship onto a truck orfreight car body or other supporting structure expeditiously and withrelative ease and transported any desired distance over rough roadwayswithout danger of relative shifting and misalignment of the spools.

Other objects and advantages of the present invention willbecomeapparent from a study of the following descript-ion and drawingswherein:

Figure l is a perspective of one embodiment rack or support of thepresent invention;

ing and lowering -means for the clamping members of the yarn beamsupport of Figure 3.

A preferred embodiment of the present invention is shown in Figures land 2 of the drawing. As illustrated therein the supporting framework,rack or support 1 comprises the vertical members 2, 3, 4 and 5, thelongitudinal members 6, 7 and the transverse members 8, 9, 10 and 11'.The structure is further strengthened by diagonal members or the like atthe top and base of the framework. These members are all ysecured inplace by welding or lthe like." As shown in Figure 1 of the drawing, thewinding spools or beams are supported on their iianged ends on paralleltransverse supports, or skid racks 12, 13, 14, 15, 16, 17, 18 and 19which are secured to the vertical mem-bers, The skid racks arepreferably constructed of ang-le iron and have spaced arcuate portionsor beam receiving recesses B, B. The base portion of the racks acts as asupporting means for the vertical comp-onent of force of the windingspools, S, S and the vertical portion of the angle iron restricts themotion of the winding spools fin the longitudinal direction. Movabletransverse parallel clamping members 26, 27, 28, 29, 30, 31, 32 and 33are constructed in substantially the same manner as *the transverse skidracks. They are so placed so that their arcuate portions or beamreceiving recesses C, C are directly above the arcuate portions B, B ofthe opposite skid racks. The clamping members act to restrict movementof the beams S, S in a longitudinal and vertical direction. With beamslying in place in the arcuate portions C, C and B, B of the clampingmeans and skid racks, movement in a transverse direction is restricted,The vertical members 20, 21, 22, 23, 24 and 25 are secured to thevertical section of the transverse skids such as by welding or the like.However the vertica-l members 21 and 24 are slotted in the same manneras the vertical members 2, 3, 4 and 5 to add stability to the movabletransverse parallel clamping members 26, 27, 28, 29, 30, 31, 32 and 33.These vertical members act to strengthen the supporting framework yandalso to prevent any longitudinal movement of the beams within theframework 1.

In loading the beams or spools, S, S, the transverse arcuate flangedclamping members 26-33 are raised to allow suiiicient space for thebeams to be inserted in place within the bea-m supporting recesses B, B.The mechanism by which the movement of the clamping members isaccomplished is better shown in Figure 2. Reference character 30indicates one of the transverse arcuate clamping means employed in thepresent invention. Secured t-o the upper edge of the clamping means 30is a bearing plate 34 having a bore 35 which is countersunk at each endto form shoulders 36 and 37 on opposite sides of said bore. Theshoulders 36 and 37 for-ma bearing surface for the retaining knobs 38and 39 which are secured by pins or the like at spaced portions near oneend of the locking screw 40. The opposite end of the shaft has a socketconnection 41 which fits any standard size socket wrench. The lockingscrew 40 is lsupported by an internally threaded bracket 43 pivotallymounted at 43 on the vertical member 2. i

A threaded stud 44 is secured to each end of the transverse clampingmeans 30. The studs 44 are slidablev in slots 45 in the vertical members2, 3, 4 and 5 and are 'held in a predetermined posi-tion by the lockingnuts 46 that screw on the threaded end of the studs 44. When the lockingscrew is turned counterclockwise the trans` verse clamping member 30rises, guided by the studv 44 in the slot 4S. When these transverseclamping members are so raised, they give easy access to load or unloadthe beams. Each of the transverse clamping members has one locking screwthat raises or lowers said clamp'- ing means to any desired position.The main con-sidera- 3 tion in varying the size of the supportingframework 1 is that there be the same number of locking screws as thereare clamping members.

The beams S, S are loaded by placing them Von the skid racks in thespaced arcuate `portions or beam recesses B, B provided thereon and thelocking screw is turned in a clockwise direction until the arcuateportions C, C of the Vclamping members Contact the beams S, S. When thedesired relationship between the beams and the .clamping means isattained, the lock nuts on the studs are tightened to secure theclamping members in that position.

Asecond embodiment of the present invention is shown inFigures 3 and ylof the drawing. AAs illustrated therein, the supporting frame or supportSl is preferably substantially similar to the frame of the previouslydescribed embodiment and includes the fixed transverse skid racks 52which provide a suitable base or supportfor the various spools or beamsS, S and the adjustable clamping members 54 which are adapted to preventand `restrain relative movement of the beams. The slots 55a in thevertical or upright members S of the frame are preferably vertically4disposed as shown and cooperate with the studs or the like 55 adjacentthe opposite extremities of the clamping members to guide the sameduring the beam clamping and unclarnping operations. As in thepreviously described embodiment, one extremity of each of thestuds orthe like 56 is preferably threaded to receive the locking nut or thelike 56a. The plate members 57 which are secured to and extend upwardlyfrom the clamping members adjacent the spaced arcuate portions C, Cthereof are diagonally slotted as at 58 and as will vbe more apparenthereinafter are adapted to cooperate withapparatus which determines andcontrols the vertical position of each of the clamping members in theslots 55a of the upright members. Similarly the members 59 with theirbeveled Yupper surfaces 59a are also secured to and extend upwardly fromthe clamping members .and as will be more apparent hereinafter areVadapted .to facilitate movement of the same during the clamping .andunclamping operation.

The elongated shaft 60 which isV preferably Ypositioned above andsubstantially parallel to each of the clamping members 54 is journaledin the bearings or eye members '61, 62 and 63 which are secured totheframe 51 in any suitable manner. The collar members or the like 64are secured to the shaft preferably on each :side Vof the eye member 62bythe setscrews 65 as shown and thereby prevent the longitudinalmovement of the shaft.

vThe shaft which is oppositely threaded adjacent its extremities at 66and 67 is adapted to cooperate with the complementary threads of the cammembers or the'like 68`so that on rotation of the shaft the cam membersslide toward or away from one another in a grooved portion 69 of theguide members 70 which are mounted on the frame in any suitable manner.The studs or the like 71 which are preferably secured to a lower portionof each cam `member 68 cooperate with the associated slotted portions ofthe plate members 57 and therefore cause the clamping members to move inthe slots 58m response to the rotation of the shaft 60. Thus as theshaftisrotated by .a tcrank or the rlike which cooperates with thepolygonalextremity 72 of the shaft and as the cam members 681move -alongthe grooved portions of theguide members 70 the cam member studsslide inthe slottedportions of the plate member 57v and raise or lower vtheclamping membersin the slots :55a between the clamping and-unclampingpositions. The beveled membersr59 are adapted to cooperatewith the complementary beveledV lower surface '68 of the cam member 68during the clamping and .unclamping operation to facilitate the same.

While Y preferred :embodiments of the invention have been disclosed, thedescription is intended to be illustrative only and itis to beunderstood that changes 'and variationssmay be made without departingfrom the jspirit and ,scope ofthe invention as deiinedby'thepresent-clairns.
